Rechargeable batteries, how long?

Hello

I have a little problem with the charging time of rechargeable batteries.

I have a charger from the brand "clartech." However, on the "average charging times for batteries" provided by it, I don't have everything.

Let me explain

For example, for a "ro3" 550 mAh battery, the charging time is 18 hours, 240 mAh => 7 hours, 180 mAh => 5 hours.

But today, I bought rechargeable batteries that are 1000 mAh, and the manual for my charger does not specify the charging time for batteries of this type. (I should mention that I did buy "Ni-Mh" type batteries (so the same type as my charger, so there's no mistake, it's just the capacity of the battery that changes, therefore the charging time accordingly)

However, I don't know how long I should let them charge in my charger (I don't want to damage them by overcharging, and if they're not charged enough, it would only be exploiting them to half of their capacity)

I know that the higher the capacity of a battery, the longer it lasts in longevity (so less need to put it back in the charger, and consequently the charging time is longer, but by how much?

If anyone can help me figure out how long I should leave the 1000 mAh batteries in my charger to ensure they're well charged without damaging them, that would be great.

Thank you all for your responses

Romain

To ensure your accumulators are charged correctly, you multiply their capacity, given in mAh, by 1.5 and then divide the result by the current, given in mA, provided by your charger.

Example for a battery with a capacity of 2100Ah and a charger with a current of 160mA:
- a battery with a capacity of 2100 mAh x 1.5 = 3150
- charging time 3150 / 160 mA = 20 h
a proper charge usually takes 16 h.

Thank you, my guy, it's the first time I found a forum and a clear and explicit answer on the first try, it was worth a few lines.
Thanks

Thank you for this constructive response. However, I do not know what the value "1.5" corresponds to.
